Formula 1’s 2026 cars have fundamentally changed the way teams approach aerodynamics. With new regulations, active aerodynamics and a greater emphasis on electrical energy, aerodynamic efficiency has become one of the central areas of development. Against that backdrop, one seemingly minor detail on the wings of Ferrari, Mercedes and Red Bull has become particularly interesting: a series of small profiles positioned along the upper part of the wing structure.
The exact function of these elements has not been officially confirmed by the teams, so any explanation must remain a technical interpretation rather than an established fact. However, their presence fits closely with one of the defining principles of the new generation of Formula 1 cars: reducing drag first, then progressively adding downforce without sacrificing too much efficiency.
Why aerodynamic efficiency matters so much in F1 2026
The 2026 generation of Formula 1 cars must achieve a particularly delicate compromise between straight-line speed and cornering performance. The fundamental philosophy is increasingly centred on making the car as aerodynamically efficient as possible: first reducing resistance to forward motion, and then adding the downforce required for cornering without excessively compromising speed on the straights.
This philosophy is closely connected to the greater importance of electrical energy. A car capable of reaching a higher speed can enter the deceleration phase from a higher velocity and potentially manage energy recovery more effectively. Aerodynamics, power-unit behaviour and electrical-energy management are therefore increasingly interconnected rather than separate performance areas.
That relationship has already been evident in Ferrari’s 2026 development, where aerodynamic, mechanical and energy-deployment choices have become closely linked as engineers search for the most efficient overall compromise.
What are the small profiles on the F1 2026 wings?
Ferrari, Mercedes and Red Bull all feature a series of small additional elements along the upper areas of their wings, although the precise configurations differ between the cars. The interesting question is why engineers would add numerous small profiles instead of simply redesigning or increasing the loading of the complete wing.
Our technical interpretation is that these elements could allow teams to make highly localised aerodynamic adjustments. Instead of dramatically altering the complete wing profile, engineers may be able to introduce incremental increases in downforce through a sequence of relatively small modifications.
This remains a technical hypothesis based on observation of the cars rather than an official explanation from Ferrari, Mercedes or Red Bull. Nevertheless, it would be consistent with the efficiency-first approach that has become increasingly visible under the 2026 regulations.
Chord, curvature and angle: how an aerodynamic profile can change
Three fundamental characteristics help define how an aerodynamic profile behaves: its chord, its curvature and its angle. Each of these parameters contributes to the amount of aerodynamic load that a wing can produce, while also influencing the drag associated with generating that load.
- Chord: the distance between the leading and trailing edges of the aerodynamic profile.
- Curvature: the shape or camber of the profile, which influences how airflow travels around it.
- Angle: the inclination of the wing relative to the airflow.
The theory behind the small upper profiles is therefore that teams can modify the behaviour of selected areas rather than completely redesigning the main surface. Each additional element could represent a small increase in the wing’s ability to generate aerodynamic load while allowing engineers to preserve as much of the underlying efficiency as possible.
A development ‘staircase’ from efficiency to downforce
The most interesting aspect of this interpretation is that the profiles can potentially be viewed as a visual indicator of a car’s wider aerodynamic development. The more efficiently engineers can make the complete car operate, the more freedom they may have to add downforce without paying an excessive penalty in drag.
This creates the idea of a development staircase. First, engineers reduce aerodynamic resistance. Once sufficient efficiency has been achieved, another small amount of downforce can be added. Further improvements in efficiency could then make another increase possible.
According to this interpretation, as the car reaches an even higher overall level of efficiency, these small individual additions could gradually develop into something resembling a more continuous layer of the wing profile. The individual details would therefore be part of a broader evolution rather than isolated components operating independently.
This type of incremental approach is consistent with the extremely detailed development work visible throughout the current Ferrari package. Even areas such as the SF-26 rear suspension have been refined aerodynamically, demonstrating how small airflow changes can form part of a much larger vehicle concept.
Ferrari, Mercedes and Red Bull appear to follow a similar philosophy
Ferrari, Mercedes and Red Bull all display elements that can be associated with this type of solution, although each team uses a different configuration. That does not mean the three cars work in exactly the same way, but it suggests that their engineers may be pursuing a broadly similar objective: extracting additional load while retaining aerodynamic efficiency.
McLaren appears more conservative in this particular area. Under the proposed interpretation, that difference could potentially reflect a different stage of overall aerodynamic efficiency or simply a different way of achieving the same performance target.
It is important to stress that this remains an interpretation based on observation of the cars. The visible number or size of these elements cannot, by itself, provide a definitive measurement of how efficient one car is compared with another.
Why McLaren may still have something to recover in efficiency
Monza provides an additional point of comparison. Even at the Italian circuit, which presents a completely different aerodynamic challenge from the Madring, McLaren appeared to run a solution with less apparent downforce than some rival cars.
The fact that a similar pattern can be observed at two very different circuits is interpreted as a possible indication that McLaren may still have something to recover in terms of overall aerodynamic efficiency. It is not definitive proof, but the recurrence of the trend makes the comparison interesting.
Track-specific choices remain extremely important. Teams alter rear wings, flap geometries and aerodynamic configurations depending on the required balance between drag and downforce, something clearly visible in the different Ferrari and McLaren rear-wing approaches used in Madrid.
Active aerodynamics changes the entire F1 design philosophy
The central point is that the aerodynamic philosophy used on previous generations of Formula 1 cars cannot simply be applied unchanged to the 2026 regulations. Active aerodynamics and the greater role of electrical energy have altered the priorities that engineers must consider when designing and developing the car.
The car needs sufficient straight-line speed, must minimise drag where possible and still has to produce the aerodynamic load required through the corners. Those demands are not independent. Every additional amount of downforce has to be assessed against the resistance it creates and the consequences for straight-line performance and energy use.
The principle can therefore be summarised simply: efficiency first, downforce second.
That does not mean teams are deliberately building cars with limited cornering performance. Instead, the aim is to establish an efficient aerodynamic foundation from which downforce can progressively be added without creating an unacceptable drag penalty.
The small wing profiles cannot transform a Formula 1 car by themselves
It is equally important not to overstate the importance of these individual components. A small profile added to a wing cannot transform the competitiveness of a Formula 1 car on its own.
The ultimate result depends on the efficiency of the entire concept. The floor, bodywork, suspension, wings and airflow management all have to operate together. A local improvement is only truly valuable if it integrates effectively with the rest of the aerodynamic platform.
Only after reducing the overall resistance generated by the car does it become possible to add downforce progressively without paying too high a price on the straights. This interconnected approach is why seemingly minor details have become such an important part of modern development and why Ferrari’s wider SF-26 technical development extends across virtually every area of the car.
What the small Ferrari wing profiles reveal about F1 2026
The small profiles visible on the wings of Ferrari, Mercedes and Red Bull are therefore among the more intriguing details of Formula 1’s new aerodynamic era. Under the technical interpretation outlined here, they can be understood as part of a progressive search for efficiency: reduce drag first, then use that efficiency margin to add aerodynamic load.
They are not proof of one team having a definitive advantage, nor are they components capable of changing a car’s performance in isolation. Their significance lies instead in what they may reveal about the broader philosophy behind the 2026 cars.
Formula 1 has changed considerably under the new regulations. Active aerodynamics and electrical-energy demands are forcing teams to reconsider the relationship between drag, downforce and straight-line performance. In that environment, even a tiny aerodynamic profile can provide a useful clue about the technical direction engineers are taking and the philosophy shaping an entire Formula 1 car.
